HD-1036 皮革耐挠性试验机，东莞皮革耐挠性试验机，皮革耐挠性试验机厂家直销

一、皮革耐挠性试验机說明:

            使用耐橈專用夾具測試皮革表面在不斷受外力作用下皮料發生皺摺和破損的情形，本试验机用用于沙发面料的挠性试验.
 

二、皮革耐挠性试验机目的 :  

             用于沙发上的皮革如果有良好的抗弯折的特性, 生产出来的沙发便不容易起皱接, 沙发会更美观耐用.

         Purpose: If the leather use for the sofa have a good flex resistance properties, the product will have little chance to become winkle, and the product will be more durable and more comfortable.

               本皮革耐挠性试验机适用于3毫米厚度以下的皮革.

                Applicable to all types of leather below 3.0 mm in thickness.

三、皮革耐挠性试验机技術參數:

                試片: 70*45mm

                彎折角度: 22.5

               彎折速度: 100±5cpm

                計數器: 0~999,999（六位數）

                电源: 220伏300瓦
设计标准： EN ISO 5402 

 1）      Open the upper and lower clamps so that the gap is at least twice the thickness of the test piece.

打开上、下夹,其打开的夹缝应不少於待测試皮夹的2倍。

       2）      Turn the upper clamp so that its lower edge is parallel to the upper edge of the fixed lower clamp.

调整上夹使其底边跟下固定夹的上边平行。

      3）      Fold the test piece in two with the surface to be tested inwards so that the two longer sides are brought together. Clamp the folded test piece as shown in below figure （a） with the folded edge against the ledge and the end against the stop formed by the clamping screw.

将皮革沿长边对摺（测试面朝内）, 将已对摺的皮革按下图（a） 的样子,摺边搁在上夹突出的边上，末端则贴近由鎖緊螺絲造成的限位上。

把未有夹緊的那一头往外然后向下拉, 把两个里面併拢, 然后将开口端按图（c）夹緊在下夹,注意不要过份夹緊以致夹坏皮革，并且要跟对摺面垂直。

       5）      Run the machine for the required number of flex cycles selected from the following list:

Dry flex: 500；1000；5,000；10,000；20,000；25,000；50,000；100,000；150,000；

        200,000；250,000 CYCLES

 按所需测試週期开始测試。

       6）      cutting of sample: A rectangle shaped sample 70 ±1 mm x 45 ±1 mm.

       7）      样办尺寸: 70 ±1 mm x 45 ±1 mm.

      4）      Draw the free corners of the test piece outward and downward around the clamp as shown in figure （b）. Bring the inner surfaces together and clamp the free end in the lower clamp as shown in figure （c）, with the part of the folded test piece in the clamps vertical and using no more force than is necessary to make the leather just taut.
